whatever you do, don't quit your job to start a business thinking that will give you freedom and autonomy. if you believe you are called to make art, in whatever form, you have a moral obligation to make that art. aka find a boring corporate job where you can slack hella hard and work on your craft during company time.
also don't expect your art to pay your rent, because then your work will follow the market and it will suck. your spirit will suffer, too.
